2AI1FL:

 This “2 ai 1 fl ap” setting is for airplanes having two separate aileron servos, requiring 

one servo to control each aileron, and also one servo (or 2 servos on a Y-harness) that will control fl aps 
for both wings simultaneously (not available for 2-elevator tail settings).

CHANNEL ASSIGNMENTS

This function allows transmitter channels to be re-assigned to different outputs before being sent to the 

receiver. This can be useful for models having unusual confi gurations.

Some small electric fl ight models use only elevator, throttle, and rudder channels (not aileron). Here, it’s 
often preferred that the rudder be controlled with the opposite stick (right stick for Mode 2 confi gurations). 
Such channel re-assignment can be done in this screen.

Determine which Tx channel input on the left should control which output channel at the receiver as shown 
on the right. Move the cursor to the desired output on the left. Press 

ENTER

 then 

 or 

 to adjust the 

output channel as desired. Press 

ENTER

 when fi nished.

WARNINGS

Warnings can be set to alert you of undesireable switch or throttle positions when the radio power switch 

is fi rst turned on. For example, if the throttle is at full when the radio is turned on you would see and hear 
an alarm. The alarms shown can be set to “ACT” (active) or “INH” (inhibit).

Thro Pos: 

The throttle position warning sounds when the throttle stick is over 25%. Clear the alarm 

by moving the stick down. Note: if in heli mode and you have an idle-up programmed, this alarm will 
also sound to indicate that you have an idle-up switch active.

Thro Cut:

 The warning will sound when the throttle cut function is set and this switch is turned on. 

Turn off the switch to clear the alarm.

Thro Hold:

 The warning will sound when this switch is on. Turn off the switch to clear the alarm.

Flap:

 The warning will sound when the fl ap switch is in the on position but the throttle stick is too high.

TRAINER

The process of linking transmitters for wireless training purposes is explained on page 20. When in training 

mode with the TTX850 being used by the teacher, this radio can allow the teacher to transfer control of all 

or only certain 

channels to the student if desired.

Enter this screen. Press 

 or 

 to select a channel to set. Press 

ENTER

 to toggle the setting. Repeat 

with other channels as desired. Setting a channel to SLAVE means the student will have control of that 
channel when the teacher pulls the trainer switch on the master radio. Those channels which are set to 
MASTER will be controlled by the teacher at all times.

The teacher can select which switch will control the training function at the CTRL line at bottom. The control 

positions for the trainer switch can also be selected as described on page 12 (for the Control function). 

Press 

ESC

 to confi rm settings and return to the MODEL SETUP menu.

TRIM STEP SETTING

The number of degrees a servo will rotate with each increment of digital trim defl ection can be adjusted 

from very small up to large steps. Enter this screen, select the channel trim to adjust ranging from “1” for 
the smallest steps to “8” for the largest steps.
